Health
Otters are susceptible to a variety of diseases and parasites. Regular veterinary care can help keep otters healthy and extend their lifespan.
Predators
Otters are preyed upon by a variety of predators, including sharks, orcas, and large birds of prey. A healthy population of predators can help keep otter populations in check and prevent them from becoming overpopulated.
Conclusion
